Needle roller bearing ZGN357036

Install full needle roller bearings, usually with an auxiliary sleeve. At this time, the auxiliary roller or the auxiliary sleeve holds the needle to keep the needle from falling out, and the journal lifts the needle up with its own chamfering Angle. As the needle Roller Bearing moves slowly in the journal, the auxiliary roller or the auxiliary sleeve will slowly exit until it is installed to the working position. The outer diameter of the auxiliary roller and the auxiliary sleeve should be 0.1-0.3mm smaller than the diameter of the shaft. When installation, the surface coated with grease inside the bearing outer ring first, against the tight inner surface needle needle: (in the last one should be gaps), then replace the shaft neck of the roller bearing inner ring or auxiliary sleeve into the outer ring hole, and make it face alignment installed shaft end face or installed on the shaft bearing inner ring end face, and then use pressure on the press or hammer knock. The needle roller bearing can also be installed in this way. A thin layer of lubricant is applied to the outer diameter of the auxiliary sleeve, and the outer ring of the bearing is inserted into it so that the auxiliary sleeve and the outer ring of the bearing constitute an annular hole, and then the needle is installed in the annular hole. After mounting the needle roller, the auxiliary sleeve can be pushed out with the working shaft. For needle roller bearings without inner ring or outer ring, a thin layer of grease can be applied to the rolling surface of the shaft or housing hole, and the needle can be pressed against the grease of the mounting part in turn. The gap should be left when the last needle is attached. The size of the gap should be 0.5mm on the circumference of the needle bearing. The last roller can not be squeezed into, or less than one needle, because the bearing will be stuck and cannot rotate when the hard squeeze is installed; When less mounting, the gap is too large, easy to cause the rolling pin to twist and break when the bearing is running. For the needle roller bearing which only has the stamping outer ring, since the outer ring wall is very thin, the needle roller bearing should be installed with a hand hammer, and should be pressed by the press machine. Because the pressure is not uniform when the hammer strikes, it is easy to cause local deformation of the outer ring of the needle roller bearing.
